Device-mapper: Ioctl: Error Adding Target To Table Suse
use, such as if its mounted or mapped by an active LVM logical multipath error getting device centos volume. If the blacklist in /etc/multipath.conf does not restrict multipath from mapping the device, then when it gets run

during boot it will attempt to map it. Because the device is in use, this mapping will fail. Have you tried the blacklisting procedure mentioned at comment 3 in the bug? https://access.redhat.com/solutions/38538 https://bugzilla.redhat.com/show_bug.cgi?id=675366#c3 ----- Original Message ----- > From: "Jorick Astrego"
